2 Agenda Current state of affairs Why medication adherence matters Barriers to adherence Overcoming the barriers Next steps Questions 2

3 Medication adherence The degree to which the person s behavior corresponds with the agreed recommendations from a health care provider. World Health Organization 3

4 Medication adherence 22% of U.S. patients take less of the medication than is prescribed American Heart Association: Statistics you need to know. 4 Accessed November 21, 2007.

5 Statin adherence as measured by proportion of days covered (PDC) Below 80% PDC was considered suboptimal adherence. Within 3 months, mean PDC had fallen to 79%. After 3 months, 40% of patients had suboptimal adherence. After 12 months, 61% had suboptimal adherence. Benner JS, Glynn RJ, Mogun H, Neumann PJ, Weinstein MC, Avorn J. Long-term persistence in use of statin therapy in elderly patients. JAMA 2002;288:

6 Adherence to statins after two years, by condition Percent of patients continually refilling Rx 50% 40% 30% 20% 10% 0% 40% Acute coronary syndrome 36% Chronic coronary artery disease 24% Primary prevention Jackevicius CA, Mamdani M, Tu JV.

7 Why adherence matters Of all medication-related hospital admissions in the United States, 33 to 69 percent are due to poor medication adherence, with a resultant cost of approximately $100 billion a year. Results of failure to adhere to prescribed medications: Increased hospitalization Poor health outcomes Increased costs Decreased quality of life Patient death Benner JS, Glynn RJ, Mogun H, Neumann PJ, Weinstein MC, Avorn J. Long-term persistence in use of statin therapy in elderly patients. JAMA 2002;288:

8 Statin therapy adherence demonstrated to improve three specific outcomes Percent Decrease in Occurances 50% 45% 40% 35% 30% 25% 20% 15% 10% 5% 0% 46% 37% 38% 37% 32% 31% CV Death Non-Fatal MI Revascularization Compliant Entire Cohort West of Scotland Coronary Prevention Study 8 (WOSCOPS).

9 Poor adherence increases total health care costs Hypertensive Patients and Total Annual Costs Annual per-patient health care costs $12,000 $10,000 $8,000 $6,000 $4,000 $2,000 $0 $4,850 Received meds, 100% compliant $6,400 Purchased some, but took all purchased $10,500 Purchased some, taken irregularly Smith DL. The effect of patient noncompliance on health care costs. Medical Interface 1993:April;

10 Why don t patients adhere to their medication therapy? Complex therapies Side Effects Failure to understand the need for the medication High out-of-pocket costs Benner JS, Glynn RJ, Mogun H, Neumann PJ, Weinstein MC, Avorn J. Long-term persistence in use of statin therapy in elderly patients. JAMA 2002;288:

11 Overcoming barriers to adherence Health plan pays member copay Reduces member out-of pocket costs Emphasizes the importance of continuing therapy Education and outreach Explains the need for medication therapy Breaks down complex therapies into manageable parts Offers strategies for coping with side effects Benner JS, Glynn RJ, Mogun H, Neumann PJ, Weinstein MC, Avorn J. Long-term persistence in use of statin therapy in elderly patients. JAMA 2002;288:

12 The copay effect Adherence with statin therapy consistently found to be far from optimal even in populations with full drug insurance coverage. Already bad adherence to newly initiated statin therapy was further reduced by 5 percentage points as a consequence of a fixed copayment policy and a subsequent coinsurance policy.

13 Investment in medication adherence can lead to dramatic reductions in overall cost of care Average health care expenditures per year ($) $10,000 $55 $8,000 $165 $285 $404 $6,000 $763 $8,812 $4,000 $6,959 $6,237 $5,887 $2,000 $3,808 $0 1-19% 20-39% 40-59% 60-79% % Diabetes Medication Level of Adherence (% days supply/year) Rx $ Medical $ Outcome is significantly higher than outcome for % adherence group (P<0.05). Differences were tested for medical cost and hospitalization risk. Sokol M et al. Impact of Medication Adherence on Hospitalization Risk and Healthcare Cost. Medical Care. 13 Volume 43, Number 6, June 2005

14 2008 Aetna consumer research results on value-based insurance design Surveyed 1,000 individuals with 5 common conditions -- hypertension, hyperlipidimia, asthma, diabetes, and health disease. 61% of individuals found the value-based insurance design (VBID) concept extremely or very appealing. Attractiveness of VBID seems to vary by type of condition a person has -- Strongest among individuals with diabetes and asthma Mid range" for those with hypertension and heart disease; and Lower among individuals with hyperlipidimia. Appeal did not vary by income 14

15 2008 Aetna consumer research results on value-based insurance design Appeal of VBID seems to decline with increasing age about 70% of those 40 or younger find the VBID idea extremely or very appealing; Compared to less than 60% for those age, and less than 50% for those Those who find the concept appealing state financial benefits of lowered or eliminated copays as the number one reason. Results suggests that VBID will likely improve Rx compliance. 86% state they would "always" take their medication if they were participating in a value based disease management program, a 10 percent point improvement Compared to 78% who state they always take their medications currently. 15

16 Marriott International Study (2005) Although there were previous Value Based Studies, this was one of the first controlled studies and the first in a Disease Management context. Pre-post study with a comparable control group Outcomes measured Medication adherence (medication possession ratio) Cost of medication Cost of non-rx health care services Medication adherence increase significantly for 4 of 5 targeted drug categories Members out-of-pocket costs for brand-name targeted drugs decreased 27% while control group member s cost fell only 1% Prescription drug expenditures rose significantly Non-Rx medical costs decreased by roughly the same amount Overall costs for healthcare did not change significantly 16

17 Aetna Healthy Actions Rx Savings our value-based Rx plan designs Supported by Aetna s focus on evidence-based medicine and the Brigham and Women s study Drug Class Driven: copay discount based on member drug class CareEngine Powered: copay discount according to evidence-based identification for certain chronic conditions Disease Management Engagement: copay discount according to CareEngine and participation in Aetna Health Connections 17

18 Rx Savings offers a targeted copay solution Reduce copays selectively for members with chronic conditions Motivate members requiring but not receiving essential drugs to begin taking them Motivate members already taking essential drugs to remain compliant 18

19 Aetna Health Actions SM Rx Savings CareEngine-powered, Value-based Design Member claims data - history, medical claims, labs, pharmacy and demographic data is fed into the Aetna Ca reengine SITUATION A: Member already taking the Rx ACTION: Member receives targeted communication RE: reduced copay available OR SITUATION B: Member not already taking the Rx ACTION: Member and provider receive targeted communications RE: of reduced copay opportunity Report generated by CareEngine contains eligible members, drug classes, prescription and patient status Member fills Rx and pays reduced copay amount at the point-of-service Pharmacy adjudicates member Rx Member copayment level is applied after first fill at pharmacy 19

20 Rx Savings CareEngine-powered targets members with high risk conditions Medical Condition High-risk vascular conditions (including diabetes with complications) Drug Class ACE/ARBs* when needed to treat or prevent diseases of the heart and kidney Statins to lower cholesterol for those who have high risk conditions such as diabetes and coronary artery disease. Beta blockers when required for cardioprotection Diabetic medications Asthma Inhaled steroids *angiotensin-converting enzymes and angiotensin receptor blockers 20

22 Rationale for Selection of Post Myocardial Infarction Population Rationale The analysis of the Harvard model suggests that covering combination drugs for patients who have had a prior Myocardial Infarction will save both lives and money (Health Affairs, January / February 2007) Post myocardial infarction population selected due to the sequelae of medication adherence is severe regarding morbidity and mortality Evidence base is clear on the specific medications of value to this population 22

23 Proposed Research Study Aetna / Harvard Proposal Aetna to participate with Harvard in a study to formally test the hypothesis that by removing financial barriers (co-pay, co-insurance and deductibles) for certain conditions we would: Increase medication adherence Improve clinical quality Decrease medical costs 23

24 Study Description Quality improvement initiative partnering with Harvard: 3 year, 2 arm study with a control group and an intervention group Control group - no change to drug insurance coverage Intervention group - zero co-payment for ACEIs / ARBs, Statins and Beta Blockers Collaborate with plan sponsors regarding communication to members enrolled in the study Randomization will occur at the employer level 24

25 Inclusion / Exclusion Criteria Members must have Aetna Medical and Pharmacy Both FI and SI Funding arrangements will be included Excludes Medicare population Excludes members that have HSA / HRA arrangements 25

26 Outcomes Assessment Drug use and adherence Clinical Economic» composite of death from cardiovascular causes,» non-fatal recurrent infarction,» non-fatal stroke,» non-fatal congestive heart failure readmission health care costs incurred by the insurer (e.g., drug costs, event-related costs, cost of ongoing health care, costs of lost productivity) 26

27 Potential Benefits to Plan Sponsor / Members Plan Sponsor Lower medical costs Improvement in employee health care quality Improvement in employee satisfaction Decreased disability / Improved productivity Members in Intervention Group Improved health / decreased disability Decreased risk for recurrent cardiac events Medication cost savings 27
